As constituted, the Rangers are good enough to make the playoffs in an Eastern Conference stronger than last season but featuring enough lousy teams so the schedule isn’t an endless field of land mines.

Or have you not seen the Sabres, Hurricanes, Devils and Flyers?

But the question regarding and confronting the Blueshirts, general manager Glen Sather and coach Alain Vigneault is whether the personnel as currently assembled is sturdy enough to not only bring the team to the heights it scaled last year, but three victories beyond that.

Which is to suggest what might be plenty good enough to hammer Buffalo 6-1 at the Garden on a wintry Saturday night just might not be good enough to beat the big boys in a best-of-seven in April, let alone May and June.

And, by the way, let’s see how all this shakes out the next two weeks over which the Blueshirts — who have gone 10-1 while outscoring the opposition 40-17 in the past 11 — will play the Ducks, Kings, Sharks, Bruins, Blue Jackets and Penguins on the road, and the Islanders at home.

There’s a bit of a puzzle here for Vigneault, who has identified his top five defensemen and his top six forwards but has yet to define either the Rangers’ third or fourth lines through the first half of this season strangely similar to last year’s. The playoffs are not at all secured even off this run, so this is not the time for the coach to be experimenting.

But with the March 2 trade deadline just less than two months away, it is imperative the Blueshirts understand exactly what they have and what they might need. Which is why now is the time to go full throttle on both Kevin Hayes and J.T. Miller, kids in the lineup with untapped upside so the GM can lean more about both before going to market with limited assets to move and limited cap space with which to maneuver.

Hayes has been everything the Rangers could have imagined when they signed Chicago’s 2010 first-rounder as a free agent out of Boston College over the summer. The 6-foot-5 rookie with the soft hands is growing into his future role as a matchup power center. Maybe he’s the guy, for instance, that might be able to take down L.A.’s Jeff Carter.

But this year? It is going to represent a significant challenge as is for Hayes, who never has played more than 44 games in a season, to keep pace as the pace exponentially increases over the remainder of the 82-game marathon?

“My brother [the Panthers’ Jimmy Hayes], my cousins [former NHL players Keith Tkachuk and Tom Fitzgerald] and my friends have warned me about the schedule and have told me how to prepare for the second half,” Hayes said. “And our staff has been on top of it. It’s kind of impossible to get out of shape with our staff.

“I feel really good about keeping up with the pace and my execution. I’ve actually felt better in the last few games than I did before Christmas.”

Perhaps by design, perhaps through opportunity, Hayes has been more of a dispatcher the last few games too, moving the puck quickly instead of holding onto it, secure in the knowledge if he dishes, he will get it back.

“It’s a matter of trust, of trusting your teammates,” Hayes said. “It’s a quality that runs through the team.”

And it is trust that Vigneault should by now be comfortable investing in Miller, who somehow is on both the fourth line and the second power-play unit, an unusual scenario, indeed. It was Miller’s clever pass that set up Chris Kreider for the first-period power-play goal that gave the Rangers a quick 2-0 lead against a Sabres team that presented no ensuing push-back.

“You can’t be out there toe-dragging all the time but I’m playing with confidence to try and make skill plays when they’re there,” Miller said. “You have to make the smart play, but I’m not out there playing like I’m afraid to make a mistake.

“The touches on the power play are good for me, but being on the fourth line I’m also doing a lot of banging and chipping the puck for possession time, and I think we’ve done a good job of that as a unit.

“It’s not accurate to say I’m comfortable … can never get too comfortable … but I’m playing with confidence and I believe in my instincts.”

And so, even as the instinct is to suggest the Rangers will need to bulk up in order to reach the Promised Land, the next couple of weeks against fierce opposition will tell us — and, more importantly, Sather and Vigneault — whether Hayes and Miller can be a large part of the bulk down the stretch and into the playoffs.
